Write a balanced chemical equation, the ionic equation, and net ionic equation for the following a.) sulfuric acid (aq) + sodium hydroxide (aq) -> b.) nacl(aq)+agno3(aq)->

Explanation:

Chemical equation:

H₂SO₄ (aq) + NaOH (aq)      →   Na₂SO₄(aq) + H₂O(l)

Balanced chemical equation:

H₂SO₄ (aq) + 2NaOH (aq)      →  Na₂SO₄(aq) + 2H₂O(l)

Ionic equation:

2Na⁺(aq)   + 2OH⁻(aq)   +   2H⁺(aq)  +  SO₄²⁻(aq)     →  2Na⁺(aq) + SO₄²⁻(aq) + 2H₂O(l)

Net ionic equation:

2OH⁻(aq)   +   2H⁺(aq)     →   2H₂O(l)

The SO₄²⁻(aq) and Na⁺ (aq) are spectator ions that's why these are not written in net ionic equation. The water can not be splitted into ions because it is present in liquid form.

Spectator ions:

These ions are same in both side of chemical reaction. These ions are cancel out. Their presence can not effect the equilibrium of reaction that's why these ions are omitted in net ionic equation.  

2nd

Chemical equation:

NaCl(aq)     +    AgNO₃(aq)     →  NaNO₃(s) + AgCl(aq)

It is the double displacement reaction. The sodium chloride react with silver nitrate and form sodium nitrate and silver chloride.

Balanced chemical equation:

NaCl(aq)     +    AgNO₃(aq)     →  NaNO₃(s) + AgCl(aq)

Ionic equation:

Na⁺(aq)   + Cl⁻(aq)   +   Ag⁺(aq)  +  NO₃⁻(aq)     →  NaNO₃(s) + Ag⁺(aq)  + Cl⁻(aq)

Net ionic equation:

Na⁺(aq)  +  NO₃⁻(aq)     →  NaNO₃(s)

The  Cl⁻((aq) and Ag⁺(aq) are spectator ions that's why these are not written in net ionic equation. The sodium nitrate can not be splitted into ions because it is present in solid form.

Spectator ions:

These ions are same in both side of chemical reaction. These ions are cancel out. Their presence can not effect the equilibrium of reaction that's why these ions are omitted in net ionic equation.  

explanation:

metals have excess of electrons whereas non-metals have deficiency of electrons. thus, in order to gain stability metals easily donate their electrons to the non-metals.

for example, electronic configuration of sodium is and electronic configuration of phosphorous is .

when a phosphorous atom and sodium atom combine together then sodium will donate is extra one electron to the phosphorous atom. as a result there will be formation of ionic bond between sodium and phosphorous.

the reaction will be as follows.

there, are three sodium sodium atoms and each of them will donate its one extra electron to phosphorous atom. thus, the sub-shell of phosphorous gets completely filled.  

thus, we can conclude that electrons are transferred from atoms of sodium to atoms of phosphorous. this transfer makes the sodium atoms donate one electron and the phosphorous atoms to gain one electron. as a result, the sodium and phosphorus atoms strongly attract each other.
